How to do fast graphics?

[imp]

I'm trying to do some animation with a pretty good frame rate. I've heard this can be done by doing all the "drawing" onto an array of ints (where each int represents the RGB(a) values of a pixel) and then dumping the array to a Component (Frame, Panel, etc.). I haven't been able to figure out, or find any examples of, how this (displaying an array of ints to a visible Component) is done. I believe this is done by making the int array the source for an Image's ImageProducer and having the Component display that Image, but I don't have a real good grasp of how ImageProducers work. I would call myself a beginner. (I have read books & tutorials, but have not had much experience writing Java.) Any assistance or suggestions would be greatly appreciated. Thanks.

For what you want to do have a look at the Java Media Framework version 1.1 (JMF1.1), which provides enhanced processing of images and audio (many formats)

Have a look at:

Then have a look at “Generating a Movie File from a List of (JPEG) Images” at:

http://java.sun.com/products/java-media/jmf/2.1.1/solutions/JpegImagesToMovie.html

Hope this will help you out

Another alternative is:

Create an array of ImageIcon, these can be GIF or JPEG

(myImages[I]=new ImageIcone(“filename”)

Use in instance of class Timer to control frame rate
Start at Image[0]
Then repaint on the Timers actionPerformed method
Use the paintComponent method and call the image[x].paintIcon method
Finally current image = next image
